Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
You can, but you're using the wrong disc, wrong process.
Mac won't run an exe file, that is for windows.
Your printer is not officially supported for osx10.4, and canon has no software for it.What you can try however is going into the mac preferences menu, to printers, then click the little + button, and let it scan/search for the printer.
